Hades' Dogs

There are some unmarked mineral resources to find too. The first appears on the north of the Mako's map as soon as you start. It is a deposit of Thorium. Then head mostly east and a little south of the starting point to find a supply of Platinum. Then go south from there, almost directly east of the Debris, to find some Beryllium. The last two unmarked surprises are in the plain directly west of the Science station. There you will find some salvage, and the Thresher Maw that is guarding it. Stay in the Mako and keep moving to take this guy out. You should have some experience with these guys by now.

This side quest will only become available once the UNC: Cerberus side quest is completed in its entirety. When that time comes, look for Voyager, then head to the solar system called Columbia. There's a planet in this system called Nepheron. That planet is the locale of this side quest.

Take a look at the map above, and locate the Science Station, which is to the south of where you begin in your customized Mako. There's little that happens here of interest, though you should be ready and prepared to fight some armed soldiers guarding the outside of the station. You won't be able to run them over, and then can take decent damage, but they won't be able to inflict any meaningful damage on the Mako as long as you work reasonably quickly.

Once inside, you'll see a pretty standard layout that you should be used to. There's lots of items to grab, so be sure to grab them as you go (and after the enemies within are defeated), but the first thing you'll need to worry about are the enemies in the main chamber itself. These enemies shouldn't provide too much trouble for you, and there's plenty of cover all around, so make good use of it. Try your best to keep your friends alive so they draw some of the enemy fire away from you as you run around and eliminate any lasting enemy resistance. As always, keep an eye on your radar and look for any red dots. When they're all gone, so too are the enemies they represent.

After the enemies are slain, you can investigate the southern end of the science station. Both rooms have plenty of gear and other items for you to grab, but your main concern should be to hit up the Terminal on the east side. This terminal has all of the information you need, and once you grab it, you can head back to the Normandy at will. Make sure you've collected everything in the facility (using our map to make sure) so that you don't have to return. Then, head back to the Normandy once outside, ending this side quest. Almost.

When you head back to the Normandy, the side quest will come to a true end. As you go to navigate using the galactic map, you will be contacted by an agent of the Shadow Broker, who will want you to sell him the information you got from the Terminal back on the planet. You can handle this situation however you want -- just remember that the decisions you make here will give you Paragon or Renegade points (or neither), and that the decision you make here has a more over-arching affect on the game.
